Question

我正在努力让Selenium与我的Django项目一起工作。在测试期间，我可以（最终）将其保存到get页，但是由于某种原因，我无法使其登录。

这是我的（非常简单的）测试用例：

import pytest

from django.conf import settings
from django.contrib.auth import get_user_model
from django.test.client import Client

from pytest_django.live_server_helper import LiveServer
from selenium.webdriver import Remote

from users.tests.factories import UserFactory


pytestmark = pytest.mark.django_db


class TestDashboard:
    def test_site_loads(self, browser: Remote, test_server: LiveServer):
        browser.get(test_server.url)

        assert 'Welcome' in browser.title

    def test_valid_login(self, browser: Remote, test_server: LiveServer, user: settings.AUTH_USER_MODEL):
        password = 'testpassword'
        user.set_password(password)
        user.save()

        browser.get(test_server.url + '/accounts/login/')
        browser.find_element_by_name('login').send_keys(user.email)
        browser.find_element_by_name('password').send_keys(password)
        browser.find_element_by_css_selector('button[type="submit"]').click()
        browser.implicitly_wait(2)

        assert f'Successfully signed in as {user.username}' in browser.page_source

test_site_loads通过，test_valid_login失败，如果我以browser.current_url为例，它仍指向/ accounts / login /。如果使用browser.page_source查看页面源，则会看到“您指定的电子邮件地址和/或密码不正确。”在登录表单的错误列表中。

我不知道为什么登录凭据在这里失败，并且我想不出其他任何东西。

这是我在上面提到的browser.page_source（通过print之前的assert捕获）中看到的内容：

<form action="/accounts/login/" class="login auth-form" method="post"> 
<input type="hidden" name="csrfmiddlewaretoken" value="xLRQ8nZlfocyyQDlJxgLL0PUvsYLLNYNHEZ5awn8cLseQoR2XNQm4TiKOgMvcaS9"> 
<div class="alert alert-block alert-danger">
    <ul>
        <li>The e-mail address and/or password you specified are not correct.</li>
    </ul>
</div> 
<div id="div_id_login" class="form-group">
    <div class="">
        <input type="email" name="login" value="ricardosoto@gmail.com" placeholder="E-mail address" autofocus="autofocus" class="textinput textInput form-control" required="" id="id_login">
    </div>
</div> 
<div id="div_id_password" class="form-group"> 
    <div class=""> 
        <input type="password" name="password" placeholder="Password" class="textinput textInput form-control" required="" id="id_password">
    </div>
</div> 
    <button class="btn btn-lg btn-primary btn-block" type="submit">Sign In</button> 
</form>

我还包括了测试的相关装置：

import environ
import pytest
import socket

from django.conf import settings

from selenium.webdriver import Remote
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

from pytest_django.live_server_helper import LiveServer

from users.tests.factories import UserFactory


env = environ.Env()


@pytest.fixture
def browser() -> Remote:
    driver = Remote(
        command_executor=env('SELENIUM_HOST', default='http://selenium:4444/wd/hub'),
        desired_capabilities=DesiredCapabilities.FIREFOX
    )
    yield driver
    driver.quit()


@pytest.fixture
def test_server() -> LiveServer:
    addr = socket.gethostbyname(socket.gethostname())
    server = LiveServer(addr)
    yield server
    server.stop()


@pytest.fixture
def user() -> settings.AUTH_USER_MODEL:
    return UserFactory()

作为健全性检查，我尝试添加一些额外的print语句来检查assert之前的所有内容：

    print('User email: ' + user.email)
    print('User is active? ' + str(user.is_active))
    print('Password valid? ' + str(user.check_password(password)))
    print('URL: ' +browser.current_url)

给我：

User email: rparsons@yahoo.com
User is active? True
Password valid? True
URL: http://172.19.0.6:44025/accounts/login/

我还尝试添加一个绕过Selnium的额外测试，以尝试进一步隔离问题：

class TestAccountLoginView:
    def test_valid(self, client, user: settings.AUTH_USER_MODEL, request_factory: RequestFactory):
        password = 'password'
        user.set_password(password)
        user.save()

        response = client.post('/accounts/login/', {'login': user.email, 'password': password})

        assert response.status_code == 302

这可以按预期工作，并且可以正常登录。

更新

看起来像这样实际上与pytest-django的LiveServer有关。忽略live_server固定装置，并使用Django的StaticLiveServerTestCase，我可以很好地登录：

class TestDashboard(StaticLiveServerTestCase):

    @classmethod
    def setUpClass(cls):
        cls.host = socket.gethostbyname(socket.gethostname())
        super().setUpClass()
        cls.selenium = Remote(
            command_executor='http://selenium:4444/wd/hub',
            desired_capabilities=DesiredCapabilities.FIREFOX
        )
        cls.selenium.implicitly_wait(10)

    @classmethod
    def tearDownClass(cls):
        cls.selenium.quit()
        super().tearDownClass()

    def test_login(self):
        get_user_model().objects.create_user(username='testuser', email='test@example.com', password='password')

        self.selenium.get('%s%s' % (self.live_server_url, '/accounts/login/'))
        username_input = self.selenium.find_element_by_name("login")
        username_input.send_keys('test@example.com')
        password_input = self.selenium.find_element_by_name("password")
        password_input.send_keys('password')
        self.selenium.find_element_by_xpath('//button[@type="submit"]').click()

        assert 'Successful' in self.selenium.page_source

不太确定为什么pytest-django的LiveServer会这样做，但是至少我现在有地方可以查看。

Selenium无法登录到Django LiveServerTestCase
